BACKGROUND: The role of general practitioners (GPs) in skin cancer care is increasing. Previous, hospital-based studies suggest that GPs might not have the capabilities to gain responsibility concerning skin cancer care. OBJECTIVES: To evaluate the current approach of GPs towards skin lesions suspected of malignancy in the Netherlands. METHODS: In three general practices, all consultations in 2015 concerning skin lesions suspected of malignancy were identified and reviewed...

Trichostasis spinulosa is a rarely diagnosed disorder of the pilosebaceous unit, characterized by retention of telogen hairs within the dilated follicles. A hair tuft can be seen protruding from the follicles. We present a case of trichostasis spinulosa associated with intradermal melanocytic nevi, where dermoscopy helps to identify this entity.

BACKGROUND: Frontal fibrosing alopecia (FFA) is an inflammatory condition of the scalp, which leads to scarring and slowly progressive recession of frontotemporal and/or frontoparietal hairline. Choice of FFA treatment is highly dependent on accurate assessment of disease phase, as medical treatments are effective only during the initial inflammatory stage. METHODS: To objectively quantify the activity of the inflammatory process in FFA, 22 female patients were examined by both infrared thermography and optical dermoscopy before tissue sampling...

Dermoscopy has a high diagnostic accuracy in pigmented and nonpigmented malignant and benign skin tumors. These microscopic in vivo examinations with polarized and nonpolarized light are effective in the early detection of malignant skin tumors and reduce the number of unnecessary excisions of benign skin tumors. The selection of the skin lesions is crucial for the diagnostic accuracy of the dermoscopic examination. Not only large pigmented skin lesions, but also small hypo-, de-, or nonpigmented skin lesions, should be examined dermatoscopically as well as skin lesions that have changed in shape and/or color...

The diagnosis of pigmented actinic keratosis (PAK) is often challenging because of overlapping features with lentigo maligna. OBJECTIVE: To investigate dermoscopic patterns of PAK according to their different evolutionary stages, and to correlate the pattern with clinical characteristics of the patients. METHODS: Descriptive and analytical study of 232 PAK. Dermoscopic patterns were divided into two categories: the follicule surroundings' abnormalities (FSA) and follicular keratosis' abnormalities (FKA)...

Syringocystadenoma papilliferum is a benign adnexal neoplasm frequently seen in association with other adnexal tumours. We report the dermoscopic features of three cases of syringocystadenoma papilliferum developing in naevus sebaceus. Clinically the lesions were characterised by exophytic papillary structures. Dermoscopically, polymorphous vessels were the prevalent feature.

Non-melanoma skin cancer (NMSC), including basal cell and squamous cell carcinomas, is the most common form of neoplasm. The incidence of NMSC is increasing worldwide. The cure rate is high with early detection and appropriate treatment. Visual examination is the first screening tool used by clinicians, but it is sometimes not sufficient to discriminate benign from malignant lesions. Skin biopsy with histopathology is the gold standard for differential diagnosis; however, this procedure is invasive and occasionally painful...

Early detection is a key strategy for reducing the mortality and economic burden associated with melanoma. Dermoscopy is a non-invasive and cost-effective tool for melanoma diagnosis, which has been shown to be a reliable and sensitive method for detecting early-stage skin cancer and reducing the number of unnecessary excisions. Patients at high risk of developing melanoma require long-term surveillance. Use of digital dermoscopy follow-up of these patients has led to improved outcomes. Combined follow-up programmes using total-body photography and digital dermoscopy have led to further improvements in early diagnosis and diagnostic accuracy...

Most dermatologists are aware of the benefits of dermoscopy, and a few are familiar with laser-scanning confocal microscopy. Beyond confocal, there are fully 11 different categories of optical techniques that have been applied to clinical dermatology. This article first provides a comprehensive tabular overview of all these optical diagnostic technologies and then details 4 of the lesser known innovations that are already available or still in development (laser Doppler and speckle imaging, Raman spectroscopy, multiphoton microscopy, photoacoustic tomography), with some potential applications in clinical dermatology (blood flow monitoring, skin cancer diagnosis, composition measurements in atopic dermatitis, skin rejuvenation measurement, and noninvasive sentinel lymph node assessment in melanoma)...

Dermoscopy is a skin surface microscopic technique allowing specular reflection free observation of the skin, and has been used to examine pigmented skin lesions. However, dermoscopy has limitations in providing depth information due to lack of 3D resolution. In order to overcome the limitations, we developed dermoscopy guided multi-functional optical coherence tomography (MF-OCT) providing both high-contrast superficial information and depth-resolved structural, birefringent, and vascular information of the skin simultaneously...

BACKGROUND: Among skin neoplasms, solitary pink tumors represent challenging lesions in clinical practice since they can mimic melanocytic and nonmelanocytic lesions or even inflammatory ones. OBJECTIVE: In this case series we described dermoscopic and confocal features of 2 couples of similar lesions in order to achieve the correct diagnosis and the best therapeutic approach. METHODS: During clinical routine practice, 2 couples of clinically and dermoscopically similar lesions were examined by means of confocal microscopy...

Tinea capitis is the most important superficial fungal condition in children. It is often unrecognised but the presence of alopecia, scale and lymphadenopathy, especially in inner-city children should prompt investigation. An understanding of changing epidemiology and prevalence of causative organisms is important in deciding appropriate therapy. The use of diagnostic aids including dermoscopy is increasing and is reported to be helpful in identifying subtle signs. Trichophyton tonsurans accounts for the majority of cases in the UK and terbinafine is increasingly advocated as a safe and effective therapy...

Bier spots are asymptomatic white anemic macules with irregular shape located on the upper limbs and less often on the lower limbs and trunkus. They are observed predominantly in youg males and may be idiopathic or associated with other conditions. We report two cases with Bier spots in which videodermatoscopy and nailfold capillaroscopy were performed. Patient 1 was a 34-year-old otherwise healthy male who presented with white spots on his upper limbs for 10 years. Dermoscopy revealed marked narrowing of skin capillaries within the borders of white macules whereas capillaroscopy pattern was normal...

Trichomycosis axillaris is a common but underdiagnosed condition of the skin. The dermoscopic image of this disease is not previously described in the scientific literature. We believe that dermoscopy is a convenient and interesting diagnostic method that may aid in the diagnosis.

Dermatologists are often faced with the challenge of patients presenting with non specific symptoms such as itching and or erythema. These symptoms may be attributed to a number of diseases, many of which are trivial, and others even life-threatening. In order to establish the correct diagnosis, dermatologists must rely on good diagnostic tools and knowledge. Dermoscopy was introduced mainly for inspection of pigmented lesions, but its use has now also spread to non-melanoma skin cancer, inflammatory diseases, and almost any skin disease...

Sebaceous carcinomas are rare but potentially fatal malignant adenocarcinomas with varying degrees of sebaceous differentiation. Several dermoscopic findings of extraocular sebaceous carcinomas have been reported; however, there are no previous reports of ocular sebaceous carcinomas detected using dermoscopy. We present a case of ocular sebaceous carcinomas showing specific findings from dermoscopy, and describe the common dermoscopic characteristics. In our cases and a review of cases in the literature, we noted that polymorphous vessels and yellowish areas were observed in all eight cases...
